J.Herris German Aircraft of Minor Manufacturers in WW1. Vol II (A Centennial Perspective on Great War Airplanes 50)

Karl Krieger

   Karl Krieger, born on 26 December 1885 in Crefeld, was the Emperor's chauffeur. He had first exhibited a model aircraft at the ILA in Frankfurt in 1909. Krieger used the pseudonym "Krieger" for this, as his official position did not allow him to be active part-time.
   Shortly afterwards he was on his own request released from his duties as chauffeur so that he could devote himself entirely to aircraft construction. When the Johannisthal airfield was built, Krieger first moved to the "old take-off site", set up a workshop, and in 1910 built a monoplane, with which he only achieved short flights. His main income, however, came from flying aircraft of other companies.
   One year later, namely on September 12, 1911, Krieger took of with his own new, improved monoplane and fulfilled the conditions for the acquisition of the pilot license (# 113). In 1912 he built a Taube monoplane and in 1913 another monoplane with a 100 hp Benz engine.
   In the following month he trained student pilots and took part in almost all national flying competitions.
